Jesus FreakJesus freak, a pejorative term for those involved in the Jesus movement of the late 1960s and early 1970s, was quickly embraced by some and soon broadened to describe a Christian subculture throughout the hippie and back-to-the-land movements that focused on universal love and pacifism, and relished the radical nature of Jesus' message. Jesus freaks often carried and distributed copies of the "Good News for Modern Man," a 1966 translation of the Bible that fit the bill by including only the New Testament in its initial editions, and by being in modern English. It is currently a pejorative term for Evangelical Christians.

The term occurs in the lyrics of Elton John's song "Tiny Dancer" (referring to Gospel tracts), and it has also appeared in Felt's 1986 single "Ballad of the Band." The term has recently been used frequently by Ted Turner and Howard Stern, referring mainly to fundamentalists.
Another use of the phrase was in Kevin Michael's song "We All Want The Same Thing": "DJs in the club, Jesus Freaks and thugs, we all want the same thing." Black Sabbath (Ozzy Osbourne) in "Under the Sun" also used the phrase.

In Australia, and other countries, the term Jesus freak along with Bible basheris still used in a derogatory manner, especially of those groups who participate in door-knocking to convert atheists, Mormons and Jehovah's Witnesses.

The phrase is also the title of the 1995 album by dc Talk, and that album helped turn the term into more of a compliment. The song says, "What will people think when they hear that I'm a Jesus Freak? What will people do when they find that it's true? I don't really care if they label me a Jesus Freak. There ain't no disguising the truth." TobyMac of dc Talk still uses the term "Jesus Freak." In fact the term is used at least once in all three of his solo albums.

"Jesus Freaks" is also the name of a series of books published by Bethany House, a Christian publishing company, which examines the lives of Christian martyrs.

In Germany there is a Christian youth culture, which calls itself Jesusfreaks. They claim to have their roots in the Jesusfreaks from the US.

Jesus Freaks would typically wear jeans, a shirt making reference to the Bible, and, of course, a cross. Aside from obviously (ugh!) hymns, Jesus Freaks listen to any music that refers to christianity.
